SPECIFICATION forming part of Letters Patent No. 273,368, dated March 6, 1883. Application filed December 30, 1882. (No model.)

4To all whom 'it may concern Be it known that I, CYRUS KINNEY, ot'

Windsor, in the county ot' Essex and Prov-l ince of Ontario, Canada, have invented certain 5- new and useful Improvements in Knife-Scout'- ers, ot' which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, in which-,

Figure lis a perspective view of my device. Fig. Vis a longitudinal vertical section at .fr and Fig. 3 is a horizontal section at y y.

The nature of my invention relates to an improvement in devices for scouring and buffing table-knifes of that class wherein the knife is reciprocated between two polishing-surfaces; and it consists in a pair ot' cast plates having three cylinders, of cork or other elastic material, secured between them, one of which cylinders is covered or coated with an abrasive substance, as more fnll y hereinafter set forth.

In the drawings, A represents a wooden base, to which is secured a cast-iron plate, B, by means of two woodscrews, a, passing through lugs b b.

B is a plate similar in shape to the plate B, omitting thelugs, and between these two' plates three cylinders, C, of cork, are interposed and secured in position by a screw, c, passing passed in like manner between the two plain cork cylinders C C, carrying with it'enough polishing material from the cylinder C to give it after a few passes the required polish.

I do not wish to conne myself to the materials described for the polishing-cylinders, as

others may be used without departing from the spirit of my invention.

What I claim as my invention is- The elastic scourin g and polishing cylinders C C C' interposed between the plates B B', all

secured together substantially in the manner and for the purpose set forth. g

OYRUS KINNEY.
